As the Chicago Bears prepare for the 2013 NFL season, they are particularly excited about one of their newest additions and what he can do for their offense. Former New York Giants tight end Martellus Bennett joined the Bears as a free agent, addressing their big need at the position.

Chicago knew they were getting a big, athletic tight end who can make plays down field — something they have lacked since Greg Olsen left town. What they didn’t know, however, was that he would be causing such a ruckus among teammates.

Friday, as the team’s practice was delayed by a thunderstorm, the team waited indoors until later in the afternoon to start practice. Well, maybe all of that waiting around made him a bit cranky.

Bennett, from the get-go, seemed edgy. Several times he found himself engaging in an altercation with his teammates in the secondary, most notably safeties Major Wright and Chris Conte as well as cornerback Kelvin Hayden.

About an hour and a half into the practice, Bennett had already gotten himself into some heated exchanges with both Conte and Wright when he caught a short pass from quarterback Jay Cutler and was taken to the ground by Hayden — this being a big ‘no-no’ during camp.

Bennett immediately retaliated and caused the entire team to race over around the two and break them up. Before the practice ended, Bennett found himself getting into it with Wright again.

After practice, Bennett told Adam Jahns of the Chicago Sun Times:

“I turned into game mode. [But] I didn’t punch anyone. I didn’t swing.

“I am a blue-collar football player and that is what I always will be and I enjoy playing like that,” Bennett said.

Well, I’m curious to see how long this ‘blue-collar’ style will last with new head coach Marc Trestman. He doesn’t seem to tolerate much and wants things to be his way or the highway; he’s taking control early.

As for one of his teammates, he didn’t seem to have a problem with it. “We’re family and brothers. Brothers sometime fight. We’ll get through it,” Conte said.

I’m guessing a certain member of the family will be having a little sit-down with coach Trestman here soon. Training camp is no place for fights or scrums to occur. Bennett needs to save that tough, ‘blue-collar’ mentality for the season and keep himself in check around his teammates.
